[Modèle homogénéisé d'un processus hydrodynamique–mécanique couplé en milieu de double porosité]
Un modèle homogénéisé de l'écoulement d'un fluide monophasique compressible en milieu déformable double porosité, où les effets couplés mécaniques–hydrodynamiques sont totalement séparés, est obtenu. Le transfert entre la matrice et les fractures est complété par un effet péristaltique et par un écoulement du aux déformations de cisaillement. De nouvelles contraintes apparaissent suite aux effets couplés et à la relaxation de la matrice.
For the single-phase flow of a compressible liquid in a deformable double porosity medium, the closed homogenized model is obtained with a total splitting between various cross mechanic–hydrodynamic effects. The transfer between matrix and fractures is completed by the peristaltic effect and the effect of flow arising due to shearing strain. In the equation of deformations, a new stress appears being generated by the cross effects and matrix relaxation.
